It was much easier when one could claim missing miles online. I was doing just this when they changed to the current form. Got miles for one parent but with the new system I've still yet to hear a reply for my missing miles inquiry some several weeks later.

Long time since I had problems with miles posting on EY flights, but have now been waiting almost 6 months for miles with their partner Oman Air...
Keep on reminding them like every month. Etihad service is useless when it comes to this kind of issues...

I must be unlucky but Etihad never posts miles that quickly for me. I just routinely take photos of my boarding stubs and send it via email to the retro credit department, plus I call them and say that I am wanting credit. It usually takes a week for it to post. Not sure why my flights are always so delayed. I always make sure I have my Etihad number on the boarding pass.

I had the same issue, so I called up Etihad's main reservation number in the US, got connected to an agent immediately who asked for the PNR (booking reference number) and saw indeed that i had flown the flight. Said she had sent a follow-up to it and would take 7-10 days for it to post to my account. On 7th day got an email that missing miles had been posted and it also showed up on my online account.

I've had issues with Oman Air credit as well. I'm working on it. For more info PM me.
